How to stop grass growing in my raised beds?
Long time veggie eater, first time gardener. I have three raised beds which I plopped right on top of the sod, assuming that ten inches of soil would just smother the grass.
Now that you're all done laughing, I'll continue.
My various vegetables have done pretty good, but as you can imagine, it's been a battle all summer against the grass, especially as the roots are soooo deep. So, thinking about next year, how can I kill this grass? Would laying cardboard over the beds and then putting soil over the cardboard work? Should I get a bunch of that weed barrier cloth? Am I going to have to simply dig them up and pull up the grass roots by hand? Any ideas are greatly appreciated.
